This will require a script most likely.  You can use a script to perform complex operations on a Word document.  Here is an example of a script that reads tables from a document.

First add a script component to your solution.  You will need to add the interop dll for Word as a reference to the script.  To do this, right click on the script component and select "Edit Reference".  Choose the Microsoft.Office.Interop.Word reference from the GAC.

Now create a script, either double click on the Script component, or right click and select "Edit Script".

Click the green + button at the top of the Script editor to add a new script. 

Click the Validate  button to validate the script.   Now click the green + button again to add a second script.

Enter the following values in the specified fields

Name:  GetData

Parameters: Microsoft.Office.Interop.Word.Document worddoc, out string message, out Hashtable header, out System.Data.DataTable instructors, out System.Data.DataTable students

Method body:

message = string.Empty;
header = new Hashtable();
instructors = new System.Data.DataTable();
students = new System.Data.DataTable();
Microsoft.Office.Interop.Word.Table headerTable = worddoc.Tables[1];
Microsoft.Office.Interop.Word.Table instructorTable = worddoc.Tables[2];
Microsoft.Office.Interop.Word.Table studentTable = worddoc.Tables[3];

// Process header table

for(int row = 1; row <= headerTable.Rows.Count; row++)
{
    string name1 = CleanString(headerTable.Cell(row, 1).Range.Text);
    string value1 = CleanString(headerTable.Cell(row, 2).Range.Text);
    header.Add(name1, value1);
    string name2 = CleanString(headerTable.Cell(row, 3).Range.Text);
    string value2 = CleanString(headerTable.Cell(row, 4).Range.Text);
    header.Add(name2, value2);
}

instructors.Columns.Add("Index");
instructors.Columns.Add("Name");
instructors.Columns.Add("WWID");

for(int row = 2; row <= instructorTable.Rows.Count; row++)
{
    DataRow newRow = instructors.NewRow();
    newRow["Index"] = CleanString(instructorTable.Cell(row, 1).Range.Text);
    newRow["Name"] = CleanString(instructorTable.Cell(row, 2).Range.Text);
    newRow["WWID"] = CleanString(instructorTable.Cell(row, 3).Range.Text);
    instructors.Rows.Add(newRow);
}

students.Columns.Add("Index");
students.Columns.Add("Name");
students.Columns.Add("WWID");

for (int row = 2; row <= studentTable.Rows.Count; row++)
{
    DataRow newRow = students.NewRow();
    newRow["Index"] = CleanString(studentTable.Cell(row, 1).Range.Text);
    newRow["Name"] = CleanString(studentTable.Cell(row, 2).Range.Text);
    newRow["WWID"] = CleanString(studentTable.Cell(row, 3).Range.Text);
    students.Rows.Add(newRow);
}

Validate the script, when Valid, click the OK button to close the Script editor.

Now you can use the script from an automation.
